• Routing from the DMZ to the interior network only

  - by Allan

  I have a home network connected to Verizon's FIOS service. Verizon's ActionTec router is connected to the ONT via coax to establish the MOCA network. My DD-WRT router's WAN port is connected to one of the ActionTec's LAN ports. The DD-WRT router is configured with a static IP address and assigned to the DMZ (this is done so I only have to configure port forwarding once). My issue is that this does not allow computers connected to the DD-WRT to serve streaming audio/video to the MOCA network using Verizon's Media Manager. I know that Media Manager uses ports 18001, 5050, and 5060, but I don't know how to forward those ports so that they are only available to the ActionTec's network and not the rest of the internet.

• ASUS K55VM Laptop unexpectedly shuts down

  - by Abhishek Sha

  I've read quite a few questions on SuperUser of people having laptop shutdown problems but mine is different. My laptop specs: Intel Core i7 3610QM (IvyBridge) NVIDIA GT630M 2GB and Intel GMA4000 8GB RAM Windows 7 64 Bit My laptop occasionally shuts down when playing FarCry 3. It's around 5 months old. I've played games like Crysis and it never shuts down unexpectedly. Since I experienced this shut down recently, I decided for GPU-Z to log the temperatures. The final log value at the time of shutdown were thus: GPU Core Clock [MHz] - 797.3 GPU Memory Clock [MHz] - 896.8 GPU Temperature [°C] - 89.0 GPU Load [%] - 99 Memory Controller Load [%] - 36 Video Engine Load [%] - 0 Memory Usage (Dedicated) [MB] - 535 Memory Usage (Dynamic) [MB] - 53 VDDC [V] - 1.0620 My drivers are up-to-date and I didn't encounter any BSODs at the time of shut down. It simply turns off.

• Incident Management-Monitoring Ideas

  - by sprsr

  Hello all, What we are tring to do at our company (banking industry) is to apply some ITIL (Information Technology Infrastructure Library) principles and I need some ideas to develop our incident management system of our company. For those who have experienced with incident management, what are the things that helps you most ? What are the things that you can't live without while managing the incidents. Do you have some good screenshots of such a monitoring software ? Since we choosed to develop our own system instead of buying a big system, there are lots of things we may miss, and we are brainstorming here. I need some key points that most crucial in incident management and monitoring. Thanks.

• Please recommend tools for PC, browser, home network performance problems?

  - by mobibob

  My client is experiencing some odd response behavior in their browser for the past few days. Classic, "nothing has changed" so I am starting at ground zero. Browsing a website will timeout or take a ridiculous time to load -- other times, the same site and query is immediately responsive. Once a connection is established, video streams are uninterrupted. The home network hosts a website, but it is not experiencing any activity in Apache's 'access.log' I am using speedtest.net to check if the ISP through the internet is 'OK' -- which looks typical (average +/-). I have to suspect the home network is beaconing or something very abnormal, but I don't know where to start.

• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• Extract MP3 URL from a SWF file

  - by Charles

  I have a SWF file that basically shows a streamer, and it plays a song (I'm guessing it's MP3) that it links to, somewhere. I know the audio isn't embedded in the file since the SWF's file size is ~370KB. With most flash FLV and MP3 players, Internet Download Manager catches the URL as soon as the video/audio starts to load, and I can easily download it using IDM. In this case, IDM doesn't seem to sense anything - so I thought maybe I could extract the MP3 location myself. I tried decompiling the SWF file, as I'd heard before that with some files, decompiling can help in breaking down a file and getting just the info you need - but I honestly don't know what to look for in this particular file. Suggestions?

• No sound through DisplayPort

  - by Chris Koknat

  I'm trying to connect my Elitebook 8440p laptop to my Samsung HDTV. The laptop does not have a HDMI connection, but it does have DisplayPort. I bought a DisplayPort-to-HDMI adapter here http://www.amazon.com/gp/product/B002CSRFD8/ref=oss_product, and connected it with a 3' HDMI cable. The video shows up fine, but there is no audio. DisplayPort, HDMI, and the adapter all support audio. I contacted HP tech support, who told me to update my sound drivers. I installed the driver and rebooted. Supposedly, I should see a "HD Audio" tab. No luck, even after installing the driver again and rebooting. HP closed the case. I'm using XP Pro.

• Problem with blue-sceens

  - by Oystein

  Hi I have a problem with my computer. I get bluescreens a lot. I get different bluescreen-codes everytime, and this happens randomly. This can happen when I boot my computer, when I'm surfing on the internett, when I'm away from the computer and are logged out... I tried to disconnect everything that was connected to my computer, beside the monitor. That didn't help. I have reinstalled Windows, changed memory, changed video card, but nothing of this helped, I still get bluescreens. I guess the problem here is the mothercard, CPU or HDD. But I want your opinion before I order anything new to my computer. Can you tell me what the problem is?

• Backup and restore MySQL database without system access

  - by Sencerd

  Hi guys, I am trying to move a database from 1 provider to another, the problem is that I don't have system access at either end (ie, no ssh), so I cannot use a mysqldump. I have already tried using MySQL Administrator, the backup took about 45 minutes, but when it came to restoring it was moving at a snails pace, and estimating 12+ hours. This is a live app so I need to keep the downtime to an absolute minimum. The database consists of 35 tables, a mixture of MyISAM and InnoDB, the whole thing comes to about 4.4GB. The source and destination databases are both running on very powerful servers. Any suggestions on a quick way of doing this will be gratefully received. Thanks

• Ubuntu Server login not recognizing the keyboard after entering username.

  - by Jeff Malewski

  I'm having similar issues with logging into ubuntu server. chief problem is that once I enter my user name & hit enter, I can't enter anything ffor my password - it won't accept any keystrokes until I press Ctrl+any key. Once I've pressed Ctrl+ any key, I'm able to type again, but have never been able to enter any more than 3 characters before the 60 sec time limit. This problem is present on fresh installs of both 10.04 & 9.10. Part of the problem is lkely to be my antique pc which is an old Emachines Trigems I850 based mbd and an equally ancient Nvidia 4x AGP video card. Initially I was going to install Ubuntu 10.10, but with ORCA running with both screen reader and full screen magnification crashed the system & smoked a stick of Rambus memory. Is there any fix to this problem? Jeff

• Source of Unexplained Requests in Server Logs

  - by Synetech inc.

  Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.

• Gentoo on Mac Mini - can't get framebuffer to work

  - by user42055

  I have the latest Gentoo on an intel mac mini with 945G graphics. I'm trying to start X (with no config) but it complains that /dev/fb0 doesn't exist. I've tried adding the following options to the kernel boot params: video=intelfb:mode=800x600-32@60,accel,hwcursor vga=761 Because I read that the fb might not be enabled unless you set a vga= option. Unfortunately the kernel doesn't recognise that option. If I changed it to vga=ask it presents me a list of about 6 text modes no greater than 80x60. In the kernel I have agpgart, drm (using i830 module) and vga text console compiled in. What am I not doing right ?

• How to proxy and encrypt all my internet traffic with Win7 and Win2008R2?

  - by Malartre

  Hi, I have a Windows 7 laptop and a Windows 2008 R2 server. How can I encrypt and route all my internet request from the Win7 laptop to the Win2008R2 server? I guess the server would be called a proxy? Goal is to prevent unencrypted network snooping. I found this article about using SSH, but I would prefer an official windows integrated solution. What's the Microsoft "way" on this? http://lifehacker.com/237227/geek-to-live--encrypt-your-web-browsing-session-with-an-ssh-socks-proxy I would like this to work for all internet traffic, not just browser traffic and I would like to set this up on many Win7 clients.

• NTFS Error - file system structure is corrupt and unusable

  - by SomeGuy

  My Windows 7 (64) keeps completely locking up, and I have to hold the power button to shit it down. Event logs are showing EventID 55. I realize that this can be a warning sign of an impending disk failure, but my data on this machine is safely backed up and I don't feel like taking the time to replace the drive right now. When I have seen this problem before, I have been able to delete the offending folder with a Linux Live CD. (When CHKDSK /F didn't work). In this case, the folder is from VSS. I assume this is from Crashplan, my online backup provider. What are the ramifications of deleting this folder from Linux? Is it safe to do? "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy26."

• Why does iChat Server keep connecting to proxy.eu.jabber.org?

  - by Tom Hamming

  I have OS X Server 10.6.5 running on a new Mac Mini (server model), serving several functions among which is iChat Server (iChat and Pidgin on Windows as clients). In the iChat log in Server Admin, I kept seeing entries about connecting to proxy.eu.jabber.org. It's for our office network and I wasn't excited about external access to it, so I disabled server-to-server XMPP federation and now the connections just time out. But why is it doing that in the first place? Sample log entry: (datetime) (servername)jabberd/resolver[portnum]: [xmpp-server._tcp.proxy.eu.jabber.org resolved to 208.68.163.220:5269 (300 seconds to live) then: sending dialback auth request for route '(full server hostname)/proxy.eu.jabber.org' A couple minutes later, it comes back with: dialback for outgoing route '(full server hostname)/proxy.eu.jabber.org' timed out

• Computer won't start unless power is removed for ~5 minutes

  - by Paul Tarjan

  I have a fairly standard 2-year old desktop computer (quad-core intel, single hard drive, decent video card, 300W power supply) which recently started acting up. I'm not sure what the cause is, so hopefully you can help. Sometimes (once a week-ish) I press the power button and nothing happens. No blinking, no sounds, no nothing. If I remove the power cord (or flip the switch on the power supply) I hear a capacitor discharge. If I leave it in the "no power at all" state for about 5 minutes then I can put the plug back in and the computer works perfectly. What is the issue? What do you think I have to replace?

• About the External Graphics Card and CPU usage

  - by Balaji

  We are Rendering 16 live Streams at our client machine through one of our applications and the resolution of the video streams are as 4CIF/MPEG4/25FPS/4000Kbits. The configuration of the client machine is below. HP Desktop Machine: Microsoft Windows XP Intel (R) Core2 Duo CPU E8400 @ 3.00 GHz 2.99 GHz, 1.94 GB of RAM Intel (R) Q45/Q43 Series Express Chipset (Inbuild) The CPU usage of the machine peaks 99% for 16 streams. After some discussion, we had decided to install external graphics card to reduce the CPU usage. So that, we have tried following graphics cards. NVIDIA Quadro NVS 440 - 128 MB Radeon HD 4350 - 512 MB GDDR2 Redeon HD 4350 - 1GB DDR2 ASUS EAH 4350 Silent 1GB DDR2 But the performance wise there has been no difference - even a drop in performance. So, what is the purpose of these external graphics cards? Really it will reduce the CPU usage? What parameters have to check, if we want to reduce the CPU usage?

• Usage of two Routers on LAN

  - by brusilva

  I've currently own a Linksys E4200 and a Thomson 546v6. Because I have an IPTV service I must set the Thomson as the main router connected to the phone line so that I can distribute the video signal for 2 specific ports and the other two for LAN Access. The problem is that the Thomson doesn't like port forwards, it usually doesnt work and since I have a good router (linksys) currently only working as Access Point I would like to use it as a router itself. I don't want to do a NAT beyond NAT so my question is should I connect the E4200 and to thomson and set the E4200 as a DMZ machine and then control all trafic on the E4200 itself or is there any other option that could suit my needs better?

• How to print lots of Envelopes.

  - by Ian Ringrose

  How to print lots of Envelopes. I wish to print onto lots of envelopes: A few thousand as a one of task (may repeat each year) Good quality colour photo and graphics that has solid colour (plus some black text) Be painless to operate, I don’t wish to have to clear jams often As I need to put the envelopes into batches, I don’t need an input try that will take hundreds of envelopes. I also need to get a new colour printer to print normal A4 paper; this may or may not be the same printer. I live in the UK, if you care. What should I be looking at?

• Why doesn't the Gtalk plugin work in Firefox 3.6 betas? [closed]

  - by etlovett

  I've done a quick Google search, Bugzilla search, and glanced at Google's site for the GTalk plugin, but I can't find an answer, so I thought I'd pose the question here: On OS X, in the Firefox 3.6 betas (I'm now on beta 5, but it's been happening since at least beta 3), the GTalk plugin doesn't work for me. I've been completely unable to use video chat in GChat, which forces me to open Firefox 3.5 whenever I want to use it. This happens even after I uninstall/reinstall the GTalk plugin. Anyone know why this is happening?
